Full Description
Many developers excel at building solutions in Apex but lack formal training in the core principles of professional software engineering. This book changes that and provides a no-nonsense guide for experienced Salesforce developers ready to master the art of software design.
Pragmatic, approachable, and to the point, this book focuses on essential practices like modularity, coupling, cohesion, and testing—not just to write better code, but to improve how teams deliver software. By emphasizing object-oriented programming, dependency injection, and boundaries, it equips you to design systems that are easier to maintain, test, and scale. With fast, reliable tests as a cornerstone, you'll learn how great design enables true continuous integration and high-performance software delivery.
Through actionable examples and clear explanations, you'll learn how to design better systems, reduce complexity, and create codebases that stand the test of time. If you're serious about your craft, Clean Apex Code will give you the tools and mindset to think like a professional software engineer and deliver software at a higher level.
